Like you might think that abstract intelligence and social intelligence might carry over solidarity instead of making people more shitty in that regard. How does that even work? Why does people like that coast in life while those who they seem lesser than them suffer?
Yes, but also racism and elitism.
The smartest people from wealthy backgrounds can still absolutely despise the poor (there are people who are so ridiculously rich they can’t imagine how difficult it is to struggle with poverty; sometimes they do a challenge to see if they can survive on low wages and find out the hard way that no, no they cannot); also you have people who hear about atrocities committed against the global South and are fine with it because they identify with some Western identity.
Sometimes these people can have a struggle with their conscience (apparently Churchill said something about feeling guilt at a young age about the wars in Africa he was involved and the things he was doing, but then got over it), which is where propaganda can patch over the holes.
Racism is part of elite power structures. Those in power want to preserve it for themselves, not hand it over to non white or non cis people
Also, in those spaces you also have the non-white people who hate other non-white people (generally hate black people) and want to keep the rest down.
